Hi all,

What role do clip-begin and clip-end attributes play in computing an 
object's duration and end time?  The spec seems to be quiet on this 
issue.  The only thing it says is that "If the value of the "clip-end" 
attribute exceeds the duration of the media object, the value is ignored, 
and the clip end is set equal to the effective end of the media 
object."  But what if the object has no explicit duration or end, but has a 
clip-end property, how the computations are done in this case.  There are 
other scenarios that involve the use of the clip-* properties that are not 
covered by the spec.

Cheers
